Ok thanks, I will set up for testing connected to the garage over the weekend…
The units is currently in the garage with no reflectors in test setup. (not connected to garage motor)
Showing 0 for reflection and open door status which is as expected I believe.

Any idea on hook up points for the following unit?
Centurian Garage Doors - Australia
I believe the unit is an AVANTI MPS 12

I now seem to be getting very low reflective states from door closed, during the day. Night seems quite reasonable and high
Currently at so will have to check laser alignment when I get home
Reflection is at about 6. Door open goes to the neighbors wall… gives 0 reflection
(oops might have to look into that … )

My garage has no windows, only light would be from the top of garage etc.
No where near as much as.
